    Synology RS1221+ Rackmount

    A compact design for space efficiency

    The RS1221+ and its RX418 expansion units are designed to help you save space in compact deployments. At only 30 centimeters, half the length of a typical 2U unit, it fits perfectly snug onto 2-post or shallow rackmount enclosures. The RS1221RP+ with dual power supplies comes in at 38 cm, also fitting most shallow depth enclosures.

    • Fits into shallow rackmount enclosures
    • Easy-to-install on 2-post racks

    Built for reliability

    Redundant power

    Reduce the chance that power disruptions on a single distribution channel or PDU causes data and service availability degradation.

    Maximize service availability

    When paired with another identical unit, Synology High Availability enables automatic minute-level failover between two clustered servers in the event of a server failure to minimize service downtime.

    Data integrity and protection

    ECC memory and the Btrfs file system bring higher reliability and snapshot capabilities to help prevent data corruption and simplify data protection.

    Hyper Backup

    A comprehensive backup and recovery solution for added data protection. Create backup destinations locally, on another Synology device, rsync servers, or cloud-based destinations, such as Google Drive, Dropbox, S3-compatible destinations, and Synology C2 Storage, a dedicated backup destination for Synology devices. Deduplication, integrity checks, and incremental transfer technology reduce bandwidth and storage use.

    Snapshot Replication

    Easily schedule flexible point-in-time backups of shared folders and LUNs with an RPO as low as 5 minutes and recovery in seconds. Set up replication and failover to other Synology storage systems for fast RTOs and minimal service disruption.

    Protect your entire office with Active Backup

    The Active Backup suite enables administrators to easily secure their entire IT infrastructure by backing up mission-critical data to their NAS, including Windows & Linux workstations and servers, file servers, VMware and Hyper-V virtual machines, and Microsoft 365 and Google Workspace accounts. Benefit from deduplication, multiversioning to quickly jump back in time, and additional data efficiency optimizations for reduced bandwidth and storage use.

    Protect your entire IT infrastructure

    Run and protect virtual machines

    Synology Virtual Machine Manager (VMM) is an intuitive hypervisor application that allows users to easily set up virtual machines and run operating systems like Windows®, Linux®, and Virtual DSM. With VMM, users can create a cluster environment with multiple Synology systems while maintaining the flexibility to scale online and migrate virtual machines for load balancing and resource allocation. Disaster recovery features, including snapshots, replication, cloning, restore, and failover, help you fully protect each virtual machine and your digital assets at no additional cost.

    The VMM Pro licenses provide access to advanced features including remote replication, remote storage migration, high availability, and live migration, allowing users to further reduce the risk of service disruption and manage IT resources with maximum flexibility.

    Virtual Machine Manager VMM

    Virtualization ready platform

    Virtual Machine Manager, Synology’s native hypervisor, allows you to manage multiple virtual machines on your RS1221+ and run Windows®, Linux®, and Virtual DSM applications on your Synology NAS.

    An Effortless Virtualization Environment

    Synology’s Virtual Machine Manager adds unlimited capacity to your NAS. Configure and run many virtual machines, including Windows, Linux and Virtual DSM on your NAS to test new software releases in a sandbox environment, isolate your customers’ machines and increase the flexibility of your RS1221+ with reduced costs, both in deployment and Synology iSCSI storage fully supports most virtualization solutions to improve work efficiency with a simple management interface. VMware vSphere™ 6.5 and VAAI integration helps offload storage operations and maximize compute efficiency. ODX (Windows Offloaded Data Transfer) speeds up data transfer and migration rates, while OpenStack Cinder support turns your Synology NAS into a block storage system.

    Virtual Machine Manager

    The RS1221+ was designed with virtualization in mind. Virtual Machine Manager lets you test new software in sandboxed environments, isolate your customers’ machines, and increase your server’s flexibility.
    • Virtual DSM offers an experience as intuitive as DiskStation Manager, and offers a reliable storage solution with robust features.
    • “Multiple OS Supported” feature allows you to run Windows, Linux, and Virtual DSM on your Synology NAS with just a few simple steps.
    • Virtual machine snapshots are part of a technology offered by Virtual Machine Manager, which allows you to clone and restore a virtual machine perfectly in seconds.
    • Live Migration allows migrating Virtual DSM instances from one Synology NAS to another.
    • Flexible IT resource management allows you to distribute hardware resources such as computing power, storage space, or network interfaces across multiple virtual machines.
    • Shared environments give you the ability to create multiple isolated virtual machines for branch units or corporate services.
    • Synology iSCSI storage fully supports most virtualization solutions to improve work efficiency with a simple management interface.
